Just more syntax examples from a former test sheet of mine, if anyone needs.
By the way for testing styles first, without needing to restart the browser each time, one can just as well add a code to the adblock-stylesheet and toggle just that one on and off:
Toggle is in Tools>Privacy>Block Ads
Edit is in Edit>Configuration>Adblock-stylesheet (lies in profile folder/chrome)

css is so much easier than html. it seems opera has a better ad-blocking method. i'll have to look into that (maybe edit adblock.css but i did not know that the changes were made with out restarting neat trick..thanx

edit: I just used your code with out editing it, the web looks remnescent of ms word for dos ^_^

Of course the colors etc. are meant to be customized by yourself, just as css syntax example.
Those example colors are definitely no permanent setting for myself, I only inject this very rarely on single pages to see all links immediately jumping at me in that GLARING style, LOL!
